More than 20 members of the Royal Family will gather to mark the 60th anniversary of the Queen's coronation today with a religious service at the abbey where she was crowned.

Alongside the Queen will be the Duke of Edinburgh, the Prince of Wales and the Duchess of Cornwall. The Duke of Cambridge and a heavily pregnant Duchess of Cambridge will be among the 2,000-strong congregation at today's celebration in Westminster Abbey in London.

It will be the first time the couple, whose first baby is due next month, has attended a public event at the church since they married there more than two years ago.

Other royals present will include Prince Harry, the Duke of York, Princesses Beatrice and Eugenie, the Earl and Countess of Wessex, Lady Louise Windsor, the Princess Royal and Zara Phillips and her husband Mike Tindall.

The majestic St Edward's Crown - with which the Queen was crowned - will rest on the High Altar - the first time the heavy, solid gold, jewel encrusted crown has left the Tower of London since the 1953 coronation.

The Queen will today celebrate the 60th anniversary of her Coronation.

In 1953, more than 8,200 guests witnessed the proceedings and an estimated 27 million people in Britain watched the events unfold on television, but today the monarch is spending the anniversary privately.

She is expected to be at her favourite royal residence Windsor Castle, where she likely to attend church at a private chapel within the estate.

The Queen will listen to an address by the Archbishop of Canterbury and a reading by Prime Minister David Cameron.
